Food away from home (FAFH) consumption, particularly fast food, is linked to obesity. This study reveals fat demand is elastic, suggesting targeted policies could effectively modify FAFH choices and improve public health outcomes.
Area of Science:
- Nutrition Economics
- Public Health Policy
- Consumer Behavior Analysis
Background:
- Food away from home (FAFH), especially fast food, is implicated in the obesity epidemic due to high energy, fat, and sugar content.
- Existing research suggests consumers may over-demand nutrients in FAFH, but lacks crucial elasticity data for policy.
- The interplay between nutrient intake and bioeconomic factors like obesity and physical activity is recognized but often omitted in FAFH demand studies.
Purpose of the Study:
- To derive implicit nutrient prices and estimate demand elasticities for nutrients within FAFH.
- To incorporate the endogeneity of bioeconomic outcomes (obesity, physical activity, health status) into FAFH demand analysis.
- To assess the potential effectiveness of nutrient-based price policies and health-subsidizing interventions.
Main Methods:
- Developed a method to derive implicit prices for nutrients in FAFH.
- Employed econometric models to estimate nutrient demand elasticities, accounting for endogeneity of health outcomes.
- Utilized simulation analysis to test policy implications.
Main Results:
- Fat was identified as the only elastic macro-nutrient in FAFH demand.
- Cross-price elasticities between nutrients were found to be small.
- Simulation results supported the efficacy of nutrient-based price policies and subsidies for positive health outcomes.
Conclusions:
- Nutrient-based price policies for FAFH could be effective in influencing consumer choices, particularly concerning fat intake.
- Small cross-price elasticities suggest policies targeting individual nutrients are feasible.
- Policies subsidizing positive health outcomes may also be beneficial in addressing FAFH-related public health issues.
